WM. G. BUDLONG, OF HARTFORD, CONNECTICUT, ASSIGNOR TO HAMILTON WV. CONKLIN AND JAMES W. CORNING, OF SAME PLACE.

CARPET-SWEEPER.

Specification of Letters Patent No. 24,176, dated May 24, 1859.

To al?. whom. it may concern:

Be it known that I, WILLIAM Gr. BUDLONG, of the city and county of Hartford and State of Connecticut, have invented an Improved Carpet-Sweeper, and do hereby declare that the same is fully described and represented in the following specification and the accompanying drawings, of which- Figure l, is a top view; Fig. 2, an under side view; Fig. 3, a transverse and central section, and Fig. 4, a longitudinal section of it. Fig. 5, is a transverse section taken through one of the supporting levers of the brush.

In such drawings A, exhibits the case of the carpet sweeper while B, is a rotary brush arranged therein and having its journals a, a, extending through and supported by two levers C, C, whose fulcra n, a, are arranged in the common axis of two driving gears D, D, which are arranged respectively at opposite ends of the frame or case A, and so as to project a short distance out of the bottom of the same as shown in the drawings. The lower part of the case A, is provided with an opening b, (see Fig. 2,) through which the rotary brush extends in order that it may run in contact with the carpet when the machine is placed on and moved across the same. This rotary brush has its bristles or bunches of bristles arranged around the body part c, in spiral or helical rows as shown at cl, cl, the same being to cause the brush to more thoroughly sweep the carpet than would be the case were its bunches of bristles to be arranged in circles at right angles to the axis of the brush. Furthermore each journal of the brush carries a pinion f, which engages with one of the driving gears D, D, so that when the gears are put in rotation the brush willv also be put in revolution. The two levers C, C, at their front ends are connected together by a rod g, and each lever near its front end is supported by an adjusting screw 7L, which extends downward from the case A, and screws through the lever or a projection therefrom.

By means not only of the said levers' applied to the brush and having their fulcra in the common axis of the driving gears as described but by the adjusting screws applied to said levers the brush may be raised or lowered relatively to the bottoni of the case A, and however it may be so adjusted its pinions will be maintained in correct engagement with the driving gears. Both in front and in rear of the brush is a dust receiving drawer I, whose inner edge is furnished with an inclined lip or guard Z, which projects therefrom and lays against the brush as shown in the drawings. The-purpose of this lip being to prevent dirt or dust from being thrown out of the drawer or escaping therefrom and between the drawer and the brush during the movement of the machine while it may be in use. The lip by laying against the brush so that the latter may work in contact with it presents so broad a surface as will completely prevent the escape of dirt from its drawer.

fm, m, are small rollers or wheels for supporting the machine on a carpet. In a carpet sweeper constructed as above described we have a means not only of adjusting the brush with respect to the carpet for the purpose of causing such brush to sweep with a proper degree of pressure thereon, but as fast as the brush may wear, it may be lowered by its adjusting screws. Thus the brush may be used until its bristles are entirely worn up to the stock or body the pinions of the brush under any such adjustment being preserved in due relation or engagement with the driving gears. The said carpet sweeper when moved over a floor, will sweep it during each forward as well as each backward movement of it thereon the dirt taken up being alternately brushed into the drawers.

I claim- In combination with the gear wheel D, and pinion f, at either end of the case, the lever c, and screw 71., by which the height of the brush is adjusted and the pinion is engaged with the driving gear, arranged substantially as and for the purpose specified.

WILLIAM G. BUDLONG.
